Several Pacific Island countries have signed a joint letter in support of Taiwan's participation in the United Nations.
Leaders of the Marshall Islands, Nauru, Palau and Tuvalu joint-signed the letter with six of Taiwan's other diplomatic allies.
The news agency CNA reported the letter was addressed to the UN Secretary-General, Antonio Guterres.
It urged the UN to view Taiwan as a partner in the global fight against the Covid-19 pandemic, and in working towards Sustainable Development Goals.
The UN is called on to resolve a situation in which the 23 million people of Taiwan are excluded from the UN system, and to lift the ban on Taiwanese citizens and its media from entering UN headquarters.
Taiwan is excluded from its own UN level representation because China claims it as its province with no right to its own diplomatic representation on the global stage.
Taiwan's allies have pressed Guterres on the need for Taiwan to be allowed to participate in the World Health Assembly.
However Guterres said that he had no control over the WHA.
He also cited UN General Assembly Resolution 2758 which recognised Beijing as "the only legitimate representative of China to the UN" as the basis for Taiwan's continued exclusion at the global body.
